Heavy Duty Casters
Kingpinless™ Casters
COLD FORGED CASTER RIGS
RWM’s 46 series are manufactured from hot
rolled pickled steel designated C1015. This steel
has a higher tensile strength than the steel used in
stamped casters. The cold forging process applies
enough force to the parts to cause the molecules of
metal to flow to points of greater strength. The cold
forging process also refines the grain structure of
the steel to produce deep smooth coined ball races
which do not require machining.
While cold forging hardens the raceway to a
certain extent, To provide greater strength, RWM
case hardens all raceways of our cold forged casters.
This process provides longer wearing and easier
swiveling casters.
Cold forging provides a caster with strength
and economy in a single product. The strength and
endurance of the cold forged casters approach that
of a hot forged caster. Due to their strength, the cold
forged casters are used for many applications which
hot forged casters were formerly required.
HOT FORGED CASTERS
RWM’s 95 series is a hot forged caster. The hot
forged caster design does provide some advantages
over cold forged casters when they are built right.
Hot forged casters are manufactured from medium
carbon steel known as C1045. The increased carbon
in this steel causes the metal to be harder, gives it
greater tensile strength, and enables the metal to be
subjected to heat hardening processes.
The advantages of hot forging are that a stronger
steel can be forged into the desired shape, deeper
parts can be formed, and the grain structure of
the metal can be controlled to flow in the desired
direction to give optimum strength to the parts.
The disadvantages of the hot forging process are
that close tolerances cannot be obtained and smooth
finishes cannot be controlled unless the parts are
machined. Additionally, the machined parts are of
no advantage over cold forged parts unless they are
hardened. RWM flame hardens its hot forged caster
ball raceways which gives the raceways longer
wearing characteristics and still leaves the forged
metal in a tough state without stress risers. The
hardness of hot forged flame hardened raceways is
550 Brinell vs. 500 Brinell of cold forged raceways.

PROBLEMS WITH STANDARD KINGPIN
CASTERS
In most industrial applications, the probability
exists that in normal operation the castered
equipment will have to pass over cracks in the
floor, door sills, elevator entrances, and other floor
obstructions. The angle and force at which a caster
strikes an obstruction will have a definite effect upon
the wear and durability of the caster rig.
Factors which contribute to metal fatigue and
failure are weight, speed, and obstructions. The
higher these factors become, the stronger the
caster must be to give a reasonable service life.
Unfortunately, kingpin-style casters eventually fail in
the above conditions.
HOW FAILURE OCCURS
There are two forces that continually act upon
the caster. The direct force and the thrust force.
These forces increase several times in magnitude
whenever the caster receives a shock by hitting
an object such as a door sill or by movement over
a broken concrete surface. When this occurs,
practically the entire load is supported on the rear
portion of the bearing due to the lead or offset built
into the caster. Less than five steel balls in each
race, the load and thrust race, carry the entire load.
The thrust forces transmitted to the caster try to rip
off the yoke in the counterclockwise direction. The
rivet is the only thing that keeps the yoke intact with
the top plate. The thrust force is transmitted to the
front part of the kingpin. Again, one small area
must do all the work. Overstressing results in
the failure of the kingpin or bending of the metal
around the kingpin to the point where the caster is
no longer usable.
These problems occur with all kingpin-style
casters eventually. Not only those made by RWM,
but by our competitors as well.

SOLVING KINGPIN FAILURES WITH RWM’S UNIQUE KINGPINLESS DESIGN
RWM provides a series of casters, our 65
through 125 series that are different than any other
caster on the market today. These casters are
Kingpinless™. The major factors that differentiates
the Kingpinless™ casters from all the other casters
is, it has no kingpin. A cross-sectional view of the
RWM Kingpinless casters is shown below. The
illustrations show the bearing construction of
each raceway. The illustrations also show RWM’s
patented raceway design.
The single row of balls perform a multiple
function. They act as (1) the load carrying bearing,
(2) the thrust bearing, and (3) they maintain the
yoke in tight rolling contact with the inner race and
top plate.
KINGPINLESS CONSTRUCTION
The raceway is machined from bar stock steel
with RWM’s patented offset raceway configuration.
This eliminates any condition of the balls having
point contact with the raceways and therefore,
avoids ball indentation ( brinelling ) to the raceways.
The large load bearing diameters eliminate the
need for heavy forged construction. In addition,
the raceways are completely case hardened to
further extend the life of the caster, a process
many manufacturers choose to skip in order to cut
costs. The rig consists of three main parts: the top
plate, the inside race, and the outside race/yoke.
The minimum number of parts allows for simplified
assembly procedures, and greater flexibility in
size configurations. Also, there are fewer parts to
wear out in the kingpinless design as compared to
kingpin-style casters.
Hot Forged
Why it’s a Superior design
In direct static loading, as a load is placed on
the caster, the forces are initially transmitted to
the rearward balls. Due to the fact that the balls
ride on an incline, they tend to climb up the incline.
This pulls the yoke to the rear of the caster. As
this occurs, part of the load is transmitted around
the bearing to the front of the caster. This gives
distribution of the load over the entire swivel bearing
instead of just on the rear balls. When thrust
forces occur as when the caster is swiveled or hits
an obstruction, these forces will push the yoke
backwards in an attempt to rotate the yoke. The
yoke is pulled down on the front part of the bearing
and pushed up in the back. In this way the thrust is
distributed over the entire bearing.
